To evaluate women's choice in the method of labour induction between oral misoprostol, PGE2 pessary and the Foley catheter. To compare women's satisfaction according to their choice and to identify factors associated with patient satisfaction. MethodsWe conducted a comparative, prospective cohort study of 520 women who chose their preferred method for labour induction, in a French tertiary hospital, from July 2019 to October 2020. Before and after the delivery, they were asked to argument their choice and to evaluate their satisfaction through the use of questionnaires. The primary outcome was global level of satisfaction. ResultsOf the 520 women included, 67,5% of women chose oral Misoprostol compared to 21% PGE2 pessary and 11.5% the Foley catheter. Regarding global satisfaction, we found no signi cant difference between the three groups: 78,4%, 68,8% and 71,2% (p = 0,091) for respectively oral misoprostol, PGE2 pessary and the Foley catheter. Factors that seem to improve women's satisfaction were nulliparity (OR = 2.03, 95%CI[1.19-3.53]), delivery within 24 hours after the start of induction (OR = 3.46, 95%CI. [2.02-6.14]) and adequate information (OR = 4.21,). Factors associated with lower satisfaction rates were postpartum hemorrhage (OR = 0.51, 95%CI [0.30-0.88]) and caesarean section (OR = 0.31, 95%CI [0.17-0.54]). ConclusionWomen satisfaction rates were not different between the three methods, when chosen by the patients themselves. These nding should encourage caregivers to promote shared decision making when possible.

“…IOL in late pregnancy can reduce the occurrence of post-term pregnancy and post-term related complications, and protect the fetus from adverse pregnancy outcomes [ 8 , 15 ]. The World Health Organization recommends delivery rate within 24 h as a key indicator for evaluating the effects of IOL [ 16 ].…”

“…According to literature reports, there is no significant difference in the spontaneous delivery rate between the two methods [ 7 – 9 ]. Compared with pharmacological methods, mechanical methods are preferred for cervical ripening with fewer pain scores and less uterine hyperstimulation [ 8 , 10 – 12 ]. The mechanical methods induce uterine contractions mainly by squeezing the internal cervical os through a uterine balloon, which stretches the lower uterine segment, thereby promoting the local release of prostaglandins [ 13 ].…”

“…Besides the uterine balloon, CCRB has another balloon named vaginal balloon, which helps to fix the uterine balloon on the lower uterine segment. However, the success rate of spontaneous delivery after cervical ripening with CCRB is about 66%-70% according to the manufacturer’s instructions [ 7 , 8 ]. In this study, we evaluate a modified operating procedure of CCRB in the aim of achieving a better cervical ripening effect and improving the success rate of spontaneous delivery.…”

Background This study aims to evaluate the efficacy and safety of the modified application of COOK Cervical Ripening Balloon (CCRB) for induction of labor (IOL) at term in primipara. Methods A total of 227 singleton full-term pregnancies with indications of IOL were enrolled and randomly divided into the control and study groups in our hospital from January 2021 to December 2021. In the control group, a conventional method was used. Both the uterine and vaginal balloons were filled to 80 mL and removed after 12 h. In the study group, a modified method was used. The uterine and vaginal balloons were filled to 120 mL and 40 mL respectively. Light traction was given to help CCRB to be discharged after 12 h placement. Oxytocin was administered in both groups after CCRB was discharged before labor starting. The improved Bishop scores, duration of labor, and spontaneous delivery rate were evaluated in the two groups. Results The improved Bishop scores in the study group were 3.06 ± 0.97 at 12 h placement of CCRB and 4.37 ± 0.87 when CCRB was discharged, which were significantly higher compared to the control group (2.52 ± 0.79, p < 0.05). Duration of the first stage of labor and the full labor in the study group were significantly shorter than those in the control group ((6.17 ± 2.85) h vs. (7.27 ± 2.90) h, p = 0.010; (7.07 ± 3.18) h vs. (8.09 ± 3.11) h, p = 0.028). No difference in spontaneous delivery rate between the two groups was observed. But the delivery rate within 24 h between the two groups was significantly different (79.79% vs. 55.91%, p < 0.05). For the cases with initial Bishop scores ≤ 3, the improved score was significantly increased, the first stage of labor and the full labor were significantly shorter in the study group than those in the control group (p < 0.05). Those results were not observed in cases with initial Bishop scores of 4–6. Conclusions The modified application of CCRB could benefit cervical ripening, shorten the duration of labor, especially for cases with poor cervical maturity, and improve the delivery rate within 24 h.

“…The Foley catheter used in our study, whose history dates back to the 19th century, is also not the only mechanical method used in cervical ripening. It seems that Cook's balloon catheter, invented in the early 90's, may be more effective in preinduction cervical ripening compared to Foley's catheter and PGE2 prostaglandin [ 14 , 15 ]. Studies indicate that the combination of mechanical method with vaginal prostaglandins does not bring additional benefits such as reduction time to vaginal delivery or reduction in cesarean section rate [ 16 ].…”

Cervical assessment on the Bishop scale prior to induction of labor (IOL) is one of the strongest prognostic criteria in relation to the success of the procedure. The commonly used preinduction methods are mainly aimed at reducing the percentage of cesarean sections. Our study has analyzed obstetric results of patients who had unripe cervix (Bishop score <7) before IOL and used preinduction (Foley catheter or misoprostol vaginal insert releasing 7 mcg of misoprostol per hour for 24 hours) with obstetric results of patients in whom, due to favourable cervix, only a low-dose infusion of oxytocin was used. We reviewed the medical records of 1010 single pregnancies in whom IOL was performed. We divided the patients into two groups: group A (where preinduction was used) and group B (Bishop score ≥7 points) where preinduction was not used. Patients in group A were more likely to complete the delivery by caesarean section (OR=4.58, 95% CI 3.22-6.51), and more likely to have events that were indications for operative delivery: unreassuring fetal heart rate trace (OR=3.29, 95% CI 2.07-5.23) and arrested labor or failed induction (OR=3.4, 95% CI 2.06-5.62). The groups did not differ in the percentage of vacuum extraction, postpartum haemorrhage, and meconium stained amniotic fluid. In group B, more infants were born with umbilical cord blood pH <7.1 (1.38% vs. 0%), both groups included no deliveries of newborns with Apgar score ≤3 points, the groups did not differ in terms of the percentage of newborns with Apgar score between 4 and 7 at birth (OR=0.66, 95% CI 0.29-1.49). The immature cervix and the need to use labor preinduction is a risk factor for caesarean section. The necessity of preinduction does not impair neonatological results.
